process the process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. an increasing share of copper is produced from acid leaching of oxidized ores.
for over 30 years, ok tedi mining limited has contributed to the papua new guinea economy through mining copper, gold and silver at mt. fubilan in the western province. our success is measured by safety performance, financial performance, social development programs and the management and mitigation of environmental impacts.
carrapateena is a copper-gold deposit hosted in a brecciated granite complex and is mostly chalcopyrite with a central high grade bornite zone. the deposit is shaped like a near vertical pipe and sits under approximately 500 metres of unmineralised rock cover. more information on carrapateena geology can be found here. mining method

the process. the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. the copper(ii) ions in the chalcopyrite are reduced to copper(i) sulphide (which is reduced further to copper metal in the final stage).
once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. mining
process for obtaining analytical gold and platinum group element (pge) data from high grade ores. it is a modernized process but in its simplest form, has been in use for centuries. fire assaying is used in the determination of gold in all sample types, including drill core, soil and chip
the process of alloying—mixing other metals with pure 24 carat gold—gives malleable gold more durability, but can also be used to change its colour. white gold is created through alloying pure gold with white metals such as palladium or silver. in addition it is usually plated with rhodium to create a harder surface with a brighter shine.
copper processing: leachingis generally known), leaching, or hydrometallurgy, is carried out at lower temperatures and thus eliminates the generation of sulfur dioxide; there are, however, effluents and residues that must be treated in order to protect the environment.
concentration of copper-to-copper concentrates with copper content of less than 1%. approximately 45 dumps/dams contain approximately 791 million tonnes of tailings cover an area of approximately 9,125ha. slag waste material produced from smelting of metal concentrates. generally delivered for disposal in molten or granulated state.
generally, the finer the gold, the quicker it will dissolve. a 45 micron particle of gold would dissolve in 10-13 hours, while a 150 micron particle might take from 20 to 44 hours to dissolve in the same solution. oxygen plays an important role in the leaching of gold in a cyanide solution, also.

it is the art of encrusting gold wire (sometimes silver or copper) on the surface of iron, steel, or bronze. the surface upon which the pattern is to be traced is finely undercut with a sharp instrument. the gold thread is forced into the minute furrows of the cut surface by hammering and is securely held.
conductivity refers to the ability of a material to transmit energy. there are different types of conductivity, including electrical, thermal, and acoustical conductivity. the most electrically conductive element is silver, followed by copper and gold. silver also has the highest thermal conductivity of any element and the highest light

copper oxide + carbon ==> copper + carbon dioxide. here the copper oxide is reduced by oxygen loss, and the carbon is the 'oxygen remover' and is referred to as the reducing agent. similarly in a blast furnace, the iron oxide is reduced with carbon to free the iron from oxygen. iron oxide +

copper and aluminum are the most common materials used for wires due to their relatively low price compared with silver and gold. copper is a better conductor than aluminum and will have less voltage drop than aluminum for a given length and wire size. wire size is another important factor in determining voltage drop.
